progradation การใช้

• This process is known as progradation.
• Starting with the earliest European settlement, man has struggled with the delta s natural cycle of floods, progradation, and transgression.
• Each regressive sequence is associated with the fall in sea level which led to the progradation of the delta further into the basin.
• Factors enabling preservation include the progradation of the sabkha with sedimentation rates of 1 m / 1000 years and the creation of Stokes surfaces.
• Three large-scale lithostratigraphic units within the Tertiary have formed as the result of long-term progradation onto the Atlantic Ocean passive margin.
• Knowledge of the average rate of progradation is the basis for estimating the location of the city, which was moved every few centuries to renew its utility as a port.
• Because of the natural progradation and degradation periods, the building of the Mississippi River Delta is an integrated and long-term process that has given the region its unique mix of ecosystems, habitats and landforms.
• Master estimates the age of the crater to be less than 5000 years, or earlier than 3000 BCE, due to the deposition of sediments of the Tigris-Euphrates plain as a result of the 130 150 km seaward progradation of the Persian Gulf during that time period.
